WebJul 1, 2009 · In this paper, a virtual integrated micro-mechanics simulation tool is presented, that was developed within the framework of Crystal Plasticity (CP) theory. With this tool, a polycrystalline Finite Element (FE) model was produced by introducing grain size, orientations and distribution patterns using VGRAIN software. WebKeywords: Microstructures; Crystal plasticity; Anisotropic material; Numerical algorithms; AA6022-T4 1. Introduction To solve the balance of linear momentum governing equations of mechanics, a constitutive law for the material behavior under an applied deformation is required.
